Audiobampa11 Apr 2023 12:18Hello,
I would like to soundproof an open wooden beam ceiling. My plan is to lay a wooden layer of 20-25mm (around 1 inch) over the beams, then put a protective foil on top as a dust barrier. After that, I want to add another layer of beams with impact sound insulation attached underneath. I would like to size these beams according to recommendations to achieve good soundproofing. For the 4cm (1.5 inch) spaces between them, I’m considering filling them with sand. On top of the whole assembly, I plan to install a chipboard or OSB panel, followed by another soundproofing layer, and then floorboards, all decoupled from the walls.
Do you have any experience with this? Which materials would you recommend for soundproofing? How would you suggest transporting the sand? Is it possible to blow it in, like in sandblasting? Carrying all those bags upstairs would be quite a lot of work...!
Would it help to nail the first layer of floorboards instead of screwing them? Would it also make sense to put strips of impact sound insulation underneath? Probably best to avoid a rigid connection, since the sand should already add enough weight. Maybe someone has experience with this.
Best regards,
Bampa

Winniefred11 Apr 2023 12:42You first need to consider how much load you are allowed to apply. Old wooden beam ceilings are not designed for heavy loads. I would start there and then think further. Your construction sounds to me like it involves a significant load.

Yes, the load is still manageable. The calculation was based on a 20 cm (8 inches) concrete slab, but now we are switching to wood because concrete would have been too expensive at the site where we planned to build, considering the crane and other factors.
Therefore, I assume it should be feasible... The question is, what makes sense? Or what is commonly done?
